Kinetic and Potential Energy

1
Kinetic and Potential Energy
2
Objectives

• You will be able to define and identify Kinetic
  and Potential energy.
• You will be able to give examples of the two
  forms of energy.
• You will be able to explain how one can transfer
  to the other.

3
Potential Energy

• Energy due to position or stored energy.

4
Examples of Potential Energy
Stretching a rubber band.. -Stores energy
Water at the top of a waterfall.. -Stores
energy
YoYo in held in your hand.. -Stores energy
because of position
Drawing a Bow -Stores energy because of
position
5

• When the position of an object is altered, it
  creates Potential Energy.
• A bow doesnt have the capacity to do work,
  unless its pulled back.

6
Potential Energy Converted to Kinetic Energy
When stored energy begins to move, the object now
transfers from potential energy into kinetic
energy.
Standing still
Running
7
Definition of Kinetic Energy
The energy of motion.
8
Examples of Kinetic Energy

• Shooting a rubber band.
• Water falling over the fall.
• A Yo-Yo in motion.
• Releasing the arrow from the bow.

9
Summary of What Youve Learned..

• Example using a coin
• Holding a coin in you hand, alters the coins
  original position.
• The coin has potential energy, because it has
  ability to do work.
• Dropping the coin in the bank, changes the stored
  energy into motion.
• This transfers the coins energy from potential
  to kinetic energy.

• Pendulums and skateboarders
